A question of the type which is the favourite of JEE Advanced :-
Am I right?
For 10 s orbital doesn't make π bond right?
But considering INA and axis of p orbital, i think it should be \pi bond, no?
Something like this no?
It's non bonding combination so it should be in d
Ok, thanks a lot! The rest were fine?
a = 4 : 1,4,6,7
b= 3 : 2, 9 , 11
c = 2 ; 5,8
d = 3 : 3,10,12
ab + cd = 18
